Swallowing ability evaluation system, swallowing ability evaluation method, and swallowing ability evaluation program

摘要

PROBLEM TO BE SOLVED: To provide a swallowing ability evaluation system capable of effectively evaluating a subject's swallowing ability, a swallowing ability evaluation method, and a swallowing ability evaluation program. A swallowing ability evaluation system performs a frequency analysis of swallowing vibration data obtained by measuring a swallowing vibration of a subject's swallowing sound and/or breathing sound accompanying swallowing motion, and generates a frequency analysis data. And an index value (low frequency index value) related to the low frequency region of the frequency analysis data and an index value related to the high frequency region (high frequency index value) based on the low frequency region data and the high frequency region data included in the frequency analysis data. And an evaluation processing unit that generates evaluation data regarding the swallowing ability of the subject, including an evaluation index value determined based on a comparison result between the low-frequency index value and the high-frequency index value. And an output processing unit that performs output processing of the swallowing ability evaluation result of the subject based on the evaluation data. [Selection diagram] Fig. 3
